Precision Balls

High quality, precison made balls and related products

Quality precision balls from 0.4mm to 100.00mm diameters, made to your requirements or international standards ISO 3290, AFBMA Standard 10, and Din 5401.

Optional Certificates of Calibration or Conformance can be supplied

Calibrated Master Ball Sets

These high quality ball sets are used extensively in: Standard Laboratories, Inspection Depadments, Tool Rooms and for measuring internal grooves, tapers and setting comparators.

Each individual set can be supplied with or without its own wooden display case and certificate of calibration.

These are the ultimate ball sets for total accuracy.

  • Supplied in an attractive solid ash case.
  • Available in Standard sets of
    • 1mm to 25mm in 1mm increments.
    • 1/32 inch to 1 inch
    • To Customer specification
  • All sets can be supplied with a certificate of Calibration which lists the actual diameter for each balls.
  • In house (ISO 9002) Certificates supplied with each set.

Ball Ended Plug Gauges

Gauges are available double or single ended with Wire type handles.

Applications:
General Bore Gauging, Checking Radii, Thread and Gear Measurement.

Advantages:
Gauging is carried using a single ball diameter, and is correct irrespective of gauge alignment allowing rapid in-process checking without the risk of jammed or broken gauges.

Fixture and Checking Balls

Tungsten Carbide and hardened Stainless Steel Balls are widely used to provide locations and position reference for both manufacturing tooling and for metrology. Tungsten carbide has the advantage of high hardness 1500 – 1600 Hv, and a low coeficient of expansion.

Stainless Steel offers the same dimensional accuracy, and has a coefficient of expansion which matches most steels. It does require greater care in handling, but is prefered in some metrology and fixturing applications.


Examples shown are of our standard types, which are available in a range of sizes and configurations.

Additionally, we frequently manufacture to customers drawings and specifications.
